CHARLES W. SMITH, OF GRAND RAPIDS, MICHIGAN.

VARNISHING-MACHINE.

Application filed May 28, 1915.

To aZZ whom it may concern:

Be it known that 1, CHARLES WV. SMITH, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of' Michigan,have invented certain new and useful Improvements inVarnishing-Machines, of which the following is a specification.

My invention relates to improvements in machines for filling, paintingand varnishing rods, broom handles, carpet sweeper handles, moldings andkindred articles, and its objects are: first, to provide a machine forthe purposes stated that will distribute the filling or finishingmaterial evenly and thoroughly over the entire surface of the article;second, to provide a means whereby the filler or finishing material maybe so perfectly distributed as to preclude the possibility of any ofsaid material dripping or dropping from or forming rough spots on thearticles being treated; third, to provide a machine with which theelement that spreads and polishes the filling, finishing or polishingmaterial being spread upon the article being treated may be readilyadjusted to the diameter or size of the article being treated.

T attain these objects bythe mecl1 ani sm illustrated in theaccompanying drawing, in which- Figure l is a side elevation ofthe'machine' complete with the cap of the roller frame shown in sectionat the end to disclose the position and action of the springs thatadjust the feed rollers to the varying'forms of the articles beingtreated; Fig. 2 is an end elevation of the same,.Fig. 3 is a sec; tionalplan of the machine on the line a", m

Similar numerals and characters refer to similar parts throughout theseveral views.

This machine is made up of a vat 1 for containing the filler, varnish,paint or other material for treating the article to be treated in themachine. This vat is provided with a cover 2 that may be hinged to thevat, as indicated at 25 on Fig. 2, or may be simply placed over the vatto close it, with no hinge connection, as indicated in Figs. 1, 4. and5, and with a base 3 and foundation 4. The base of the vat is madehollow, as indicated in Figs. l and 5, for the passage of steam, hot orcold air as may be desired to hold the filler, paint, varnish or othermaterial in the vat at the proper temperature to assure the desiredresults.

The machinery in this machine by which the filling, painting orvarnishing is done consists of a tube 20 which is made revoluble thereinand is so arranged that a smaller tube 21 may be inserted therein, whichinner tube is removable, so that, when a handle of difierent size is tobe treated a tube of corresponding diameter may be inserted. This is for the purpose of averting the danger of one handle lapping by the otherin the tube and becoming clogged or wedged so they cannot be forced orfed through the tube. Both these tubes are provided with slots orelongated openings 24 through their opposite side walls, and wings orarms 23 are secured to the outer tube and have plates 22 secured thereonwith one surface of these plates so registering with the openings 24 inthe tubes that any material that may be carried up by the plates as theyare made to revolve with the tubes will, when in the position indicatedat c, discharge into the said openings and through onto the surface ofany handle or other article that may be passing through the tubes. Thuswe will presume the material to be applied to the article passingthrough the tube, fills the vat up to the dotted line b, the plates 22,when passing from a to b will carry an amount of the material up withthem, and when at o the material will be discharged through theopenings, as hereinbefore stated, and any surplus material that maydrip, or be forced off of the article being treated will pass throughthe lower opening back into the vat. As the object being treated isforced forward through the tube the forward end of the article will beforced through the opening (Z, in the rubber gasket or washer 26 andwill force this opening to expand sufliciently to allow the article topass through, but the surface of the washer will press upon the surfaceof the article with sufiicient force to remove all surplus materialtherefrom and give the surface a very smooth, polished appearance whenthe handle emerges from the tube. It is evident that with long andconstant use the opening (Z in the washer 26 will become worn andenlarged to such an extent as to become useless for the purpose forwhich it is designed. To avert this difficulty I insert a wedgingcollar, as 34, into the end of the supporting thimble 33, so arrangedthat when the opening is found to be too large the cap 30 may be screwedupon the end of the thimble 33 and force the collar 34 between thewasher and the inner surface of the thimble, thus forcing the end of thewasher to contact sufliciently to again become operative for the purposefor which it is designed, as hereinbefore explained. The thimble 33 isfirmly bolted to the end of the vat frame 1 as indicated in Figs. 1, 3and 5, and acts as a bearing for one end of the tube 20 to revolve in.

The tube 20 is made to revolve by means of a sprocket wheel 7 secured toone end thereof, and driven by a sprocket chain 8 from the smallsprocket wheel 14, mounted on the shaft 16. The-shaft 16 is driven fromthe shaft 15 by means of the gear wheels 11 and 17, and the shaft 15 isdriven from any available source of power by means of properly placedpulleys, as indicated at 9.

To force the handle 29, or other article being treated in the machine,through the tubes 2021, I provide a set of feed rollers, 6, 6, which aremounted on the shafts 28, 28 and are driven from the shaft 15 throughthe gear wheels 13,12, as indicated in Fig. 2. The lower shaft, 28, ismade stationary, so far as vertical movement is concerned, but the uppershaft is made adjustable vertically and its pressure downward iscontrolled by means of adjusting springs 18 and hand screws 19. Theseshafts and rollers are supported in the frame 5, which is secured to thefoundation 4, as indicated at 31, and the guide 10 is also secured tothe foundation so it may be adjusted vertically by sliding it up anddown in its base 32 and laterally, by turning the base laterally on itssecuring bolt 32.

To feed a handle, or other article through the machine it isplaced inthe guide 10, as indicated in Figs. 1 and 2, and passed between therollers 6, 6 and carried by said rollers into and through the tube 21,with the results hereinbefore stated. The shafts 28, 28 are mounted inboxes or bearings 27 which, in turn, are mounted on the frame 5, asindicated in Figs. 2 and 3, and the shaft 16 is revolubly mounted in theboxes or bearings 25 on the foundation. 4, asshown in Fig. 3 andindicated in Fig. 2.

I make interchangeable feed rollers for this machine, so arranged thatone set may be removed and another applied to corre- 1 spond with theform or size of any article that it is desired to pass throughthemachine.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is:
